Sumitomo 19JQBKQ Vnmg Carbide Turning Insert AC810P

Product Description

The SUMITOMO 19JQBKQ is a VNMG-style carbide turning insert engineered for precision metal cutting on CNC lathes and turning centers. Manufactured in the AC810P grade with a CVD-applied aluminum oxide (Al2O3) coating, this insert delivers wear resistance and thermal stability during continuous and interrupted cuts. The 35-degree diamond shape (Insert Shape Code V) provides a sharp, low-cutting-force geometry. The inscribed circle measures 3/8 inch (0.3750 inch), insert thickness is 3/16 inch (0.1875 inch), and the corner radius is 3/64 inch (0.0469 inch). The EUX chip breaker geometry is designed to manage chip flow across a range of feeds and depths. This insert is used by machinists and CNC operators in production turning environments.

The 19JQBKQ is suited for turning steel workpieces (ISO Material Code P / Secondary Code P) in both light finishing and moderate roughing applications. The neutral rake and neutral hand designation make it usable in standard right-hand toolholders without directional restriction. The EUX chip breaker geometry performs across a range of feed rates typically encountered in steel turning. It carries ISO code VNMG160412N-UX and conforms to ANSI and ISO 13399 standards, making it dimensionally interchangeable with other VNMG-format inserts in the same size class. Package quantity is one insert per unit.

Key Features

• AC810P carbide grade with CVD-applied Al2O3 coating for wear and heat resistance in steel turning
• EUX chip breaker for controlled chip formation across varied feeds and depths of cut
• 35-degree diamond insert shape (VNMG / Shape Code V) for low cutting force geometry
• Neutral rake and neutral hand — compatible with standard VNMG toolholders without orientation restriction
• Conforms to ANSI and ISO 13399 dimensional standards for cross-brand toolholder compatibility
• Inscribed circle 0.3750 inch, corner radius 0.0469 inch, insert thickness 0.1875 inch

Compatibility

Dimensionally compatible with VNMG-style toolholders accepting a 3/8 inch inscribed circle insert with clamp and pin holding method (Clearance Code N, Tolerance Code M). ISO code VNMG160412N-UX confirms interchangeability with other toolholders conforming to ISO 13399 in this insert size class.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Secure the insert using the appropriate clamp and locating pin for the toolholder; do not overtighten the clamp screw with impact tools. Verify insert seating and edge condition before resuming cutting operations.
